Matrix converters based on the Zeta topology

摘要

The article shows the derivation of a new matrix converters based on DC-DC Zeta converter, which aim to solve the problem of voltage gain, typical problem of this type of converters, which in the best case, is slightly higher than the unit. In a case study, obtained circuits are used as power conditioning block which is necessary to obtain a fixed level of output voltage, independent of the voltages obtained in the primary power supply frequency.
